From my understanding, you must bring a headshot (if you have one) but a simply clear snapshot of you will do. And no you can't be 16 you have to be over 16 for girls and over 18 for boys, it clearly says that guys. My only concern is that some of the dates are the same. Does that mean they are held on the same day? And do we go on both days or just one of the days?

no offence but no, you probably shouldn't ! I was thinking about going but after thinking about it, realistically I am not the movie-star style hollywood 'beautiful' that they are looking for! If you do not fit the character description exactly, I would say realistically there is not much point in going!

This forum has a lot of reviews of people who went: http://notapushymum.com/phpbb/viewtopic.php?f=14&t=20200&start=90 (I've started it from page 7, as this is where a lot of people who went commented on what happened...) There are also lots of news articles about what happened at the Bristol ones. http://www.dailymail.co.uk/news/article-2495393/Star-Wars-open-auditions-sees-hundreds-Leias-Lukes-queue.htmlThe BBC have announced the new online auditions as well, there's also more about the crowds and such in the article... http://www.bbc.co.uk/news/entertainment-arts-24896384 This why they're now changing venues and such to accommodate the amount of people. Hope this helps!
